This invention relates to new and useful inn 'n'oven'ients in a scrapersetting tool.

One object of this invention is to provide an implement of the characterdescribed specially designed for use in sharpening wood scrapers such asare used by carpenters and abinet makers for the purpose of smoothingthe surface of the work.

Another object of the invention is to provide an implement of thecharacter de-- scribed which is readily adjustable to scraprs ofdifferent thicknesses.

A further feature of the invention is to provide a device of thecharacter described which is of simple and practical construction whichmay be cheaply and easily produced by the use of which the scraper maybe quickly and easily sharpened.

With the above and other objects in view this invention has particularrelation to certain novel features of construction, operation andarrangement of parts, an example of which is given in this specificationand il lustrated in the accompanying drawings, wherein Figure 1 shows alongitudinal sectional view of the implement.

Figure 2 shows a side View thereof.

Figure 3 shows a fragmentary plan view thereof.

Figure 1 shows an enlarged fragmentary edge view of the scraper, showingthe sharpening operation completed, and

Figure 5 shows an enlarged fragmentary edge view thereof showing thesame completely sharpened.

Referring now more particularly to the drawings, wherein like numeralsof reference designate similar parts in each of the figures the numeral1 designates a hand grip, having the end chucks 2, 2, and whose ends areprotected by the metal end ferrules 3, 3.

Shanks 1 and 5 are provided, whose inner ends 6 and 7, respectively, aretapered and fitted into the respective chucks 2, 2,

The shank 4 has its outer end forked, forming the diverging fingers 8, 8whose outer ends are pointed. The scraper 9, used for scraping andsmoothing purposes by carpenters and cabinet makers is a fiatrectangular blade, formed of steel, or similar metal. This blade is runover the surface to be smoothed by hand, with the corners of either sideor end forming the scraping edge, as 10. These corners soon becomerounded off or dull, so that they will not properly do the work and mustbe sharpenc d, or set.

The shank 5 has the diverging studs 11, 11, at its free end forming anobtuse angle between them.

The numerals 12, 12 designate opposing segments which are spaced apartand are formed with the shanks 13, 13. A cross pin 14 is fixed to theshank 5 and its ends project through aligned holes in the shanks 1 andare outwardly threaded to receive the clamp nuts 14, 15 which clamp therespec tive shanks to the pin let. The segments 12 have openings, orbearings through which the studs 11 extend. If desired the inside nutsmay be dispensed with and the coil springs 15 substituted for them, asshown in Figure 3.

In order to sharpen the scraper its edges are run back and forth betweenthe diverging fingers 8, as indicated in dotted lines in Figure 1, andthis operation will upset or overturn the corners, as indicated, in anexaggerated form, in Figure 4c. The scraper is then placed between thesegments, or guides 12, as indicated in dotted lines in Figure 1, withthe corners, to be sharpened bearing against the respective divergingstuds 11, and the scraper is then moved back and forth until the saidcorners are sharpened, said corners being thrown out and formed intoscraping edges, as 10, indicated inan exaggerated form in Figure 5, andthe sharpening operation is thus completed.

The segments may be adjusted toward or from each other in an obviousmanner to accommodate scrapers of different thicknesses.

hat I claim is 1. A scraper setting tool including a shank, a gripcarried thereby, one end of the shank having diverging friction members,and spaced guides carried by said end of said shank.

2. A scraper setting tool including a shank, a grip carried thereby, oneend of the shank having diverging friction members, and spaced guidescarried by said end of said shank, said guides being adjustable towardor from each other. I

3. An implement of the character described including a grip, shankssecured thereto and projecting therefrom the outer ends of said shanksbeing formed with diverging friction members to receive a scrap-- ingblade between them.

4. An implement of the character described including' agrip shankssecured thereto and projecting therefrom, the outer ends of said shanksbeing formed with diverging friction members adapted to receive ascraping blade'between them and spaced. blade guides carried by theouterend of one of said shanks.

5. An implement of the charaeter de- 10 scribed including a grip, shankssecured thereto and projecting therefrom the outer ends of said shanksbeing formed with diverging friction members to receive a scraping bladebetween them and spaced blade guides carried by the outer endot one ofsaid shanks, said guides being adjustable toward or from each other.

In testimony whereof I have signed my name.

JOSEPH GRULLER.
